My invention consists of a steam-heat-radi ating stove, designed as an improvement upon that'made the subject-matter of another patent the application for which was filed of even date herewith. According to this invention,

one or more annular series of upright steampipes, acting as heat-radiating surfaces, are

fed by a boiler located in the base of a stove, fitting about the fuel-cylinder, and formed with upper and lower ring-chambers, the latter connected by short curved passages, which form an annular smoke-flue about the innerside of the boiler. The base of the fuel-cylinder is seated upon a circular flange. formed on the inner circumferential side of the boiler- 'castin g, approximately in horizontal line with" the top of the lower ring-chamber of the boiler, and this lowerinner circumferential side of the casting forms a continuation of the magazine-cylinder, so that the fuel burns at the base of the boiler, heating it upon its outer side, and the heated products of combustion are carried in through the spaces between the passages connecting the upper and" lower ring-chambers. The boiler is thus subjected to the action of the fire on all but its upper side, and the annular smoke-flue gives heat to the boiler in the passage of the smoke to the final-exit flue.

The base of the stove is provided with mica windows, instead of being a close-bodied metallic surface, so that an illuminated base may be afforded to the steam-heat-radiating stove. The damper-regulator for automatically controlling the heat consists of a flexible diaphragm influenced by the pressure of steam in the boiler, and connected by an intermediate rod with a lever of the third class,which latter, by suitable mechanism, operates a sliding damper. I

- Referring to the drawings, Figurel isa view, in side elevation, of mystove, Fig. 2, a central vertical section of the same. is a bottom plan of the boiler, and Fig. 4 a

sectional detail'view of the automatic heatregulating mechanism.

The boiler is formedwith the upperand lower ring-chambers-A A, connected by the short passages 13, curved outward from the fuel-cylinder O, seated in the circular flange c on the upper portion of the inner circumferential side of the lower chamber A. v The annular smoke-flue D is formed between the lower side of the fuel-cylinder andthe con ne'cting-passages B, so that as'the combustion is carried on about the outer circumference of.

the boiler the flame and products of combus' the ring-boiler continues this central fuelmagazine, and allows the fuel to burn at the base of the stove, acting against-theboiler.

as the upper fire-surface of the combustion chamber.

By making the stove with the mica windows G,I obtain an illuminated base. The connecting-passages B give the boiler an open central formation, and allow the light and flame of the inner circular flue to be seen. This, together with the combustion of the fire-cham ber', gives a brilliantillumination to the basesection through the mica lights. 1/

"The steam-pipes H may be of any size, nnm-' her, or in one or more annular series, and they extend vertically upward from the boiler, con= necting their extremities, as shown in the drawings; or they may simply have closed ends, or in any other suitable manner he formed at their upper extremities.

The heat-regulating mechanism (shown in Fig. 4) consists of the hollow metallic cylinder K, tapped into the outer margin of the upper Fig. 3 I

body of the boiler, and the hollow spherical casing K, the two securing betweerrtheir flanged connecting extremities the flexible diaphragm L. This latter is of any suitable yielding material, and is of form adapted to rest against the inner side of the saidcas- 7 ing. The short connecting-rod l passesthrough the top of the casing, and engages, by firm connection, the central body of the diaphragm. Its opposite or upper end operates the lever M, fulcrumed as a third-class lever, and actuatin g the vertical rod n, which latter operates the sliding damper N. As the steam presses against the diaphragm the latter is forced against the inner side of its spherical casing, and thus the strain upon it is transferred from its flexible body to the rigid body of the easing, and this operates to close the damper through the intermediate connections. Upon reduction of the fire incident to this closing of draft, the diaphragm is released from the strong steam-pressure before exerted upon it, and as it relaxes from its former position the damper is opened correspondingly, as is ap parent. I V a A This heat-regulatin g mechanism,- which I regard as a valuable inventi on in connection with the use of my stove, is yet applicable" in many other connections; and hence I do not claim itin thispatenabut reserve it assubject-matte'r' for ai'uture patent. V r I The stoveis provided with the reservoir attachmerit for maintaining a constant water-' level in the boiler, and a glass indicatinggage, as are fully described in my otherLettefrs Patent previously referred] to", and the present invention does not include SUCH sub ject -'matter, So, too, the stove may be adapted to convey heated air to upper room's by means of an opening in its top plate, to re ceive a pipe leading therefrom into such apartments', andthe annular series of steampipes, ekcep'tingthe outer or first series, may pass through a supporting-plate, to give themupper lateral bearing. Suitable safety-valves attached to the toner, air-vents connected with the steam-passages; and other attachments, I may supply as found desirable. y

The aslrpit and means of outer communication therewith, the ash-pamfirepot, and similar lower parts of the stove, form no part of f my invention, and the drawings are intended to represent only the material features of myimprovement.

The same mechanism for maliing the dampi er-rod detachable from its actuating device 1 may be used as is shown and described in my other patent before referred to, andthe sliding damper be held closed, even when the steam-pressure is low. T

While I have shown the stove as circular and its steam-pipes as being formed in ss la'r series, I may, instead thereof, make the same square, rectangular, or of any otherdesired horizontal section.

Having'fully described my invention, what I claim as new, and desire'to secure by Letters Patent, is y 1. A steam-radiator stove provided .with an illuminated base and a boiler partly inclosed thereby, the latter having an annular flue formed about its inner central body between upper and lower ring-chambers, and connecting by side-flue openings with the fire-chamber, substantially as described.

2. In a steam-radiator stove, a boiler having its upper ring-chamber made in full crossmeasurement of the stove, and forming a portion of its outer wall, the smaller ring-chamber being located in the fire-chamber, and the short vertically curved passa s connecting the said chambers, substantially as described. In asteam-radiator stove, a boiler having an upper ring-chamber, which forms a part of the outer wall of the stove, and the lower ring-chamber of smaller diameter, and the water-passages connecting the twoythe" said passages "being formed as shown, whereby they are subjected on all sides to the action of the fire and smoke of the combustion-chamber, substantially as described.-

4. In asteam-radiator stove, a boiler niade as" an independent easting,h'aving the' annul'ar flue within its in'n'e'rcentral body, and the side flues conseang the" fire-chamber therewith, and combined with the exit-fine, substantially as describedtg a 5". In a steam-radiator stove, a boiler haying its lower ring-chamber provided witlr the annular shoulder formed on the inner circumferenee of its upper surface, and upon which the fuel-cylinder supported, substantially as described: i

6*: In a steam-radiator stove, theboiler hay in g up er and lower ring-chambers connected by sh ort vertical passages, curved at their sides, and an annular flue formed centrally within its body, the said flue communicating with the fire-chamber through the passages which connect the ring-ehambers, substantially as de scribed;

\ A In testimo 1y that I claim the foregoing I j:have hereunto set my hand this 4th day of June, 1877. I a a p a l r VVILLI'AM H. BROWN:
